Aging and sister chromatid exchange. VIII. Effect of the aging environment on sister chromatid exchange induction and cell cycle kinetics in Ehrlich ascites tumor cells. A brief note.

To examine the effect of an aging environment on sister chromatid exchange (SCE) induction, Ehrlich ascites tumor (EAT) cells were introduced into young and old C57BL/6J mice. Background SCE levels were not significantly different in either EAT cell or normal bone marrow cell populations between young and old animals. Despite a decline in SCE induction in EAT cells was not significantly affected by the age of the animal. These findings suggest that the aging environment may not play a major role in the diminished SCE induction observed in old cell populations.
